Hi all:

Lloyd, you do speak for many of blind users who use lynx. I would love
nothing more than to be able to use lynx as my browser for my classes at
school. However, the site heavily relies on Javascript, and I am forced to
use Internet Explorer instead. I wish I could be of some help to bring
this about, but I am not a programmer. However, seems like I'm learning
HTML by looking at sorce code. I can at least interpret it, if nothing
else. If there is anything I can do to help, please let me know.
